DWDM SFP+ 1gbps OK not 10gbps

Tue Mar 07, 2017 4:43 am

Hi Guys,

I see a few threads on this floating around not sure if later F/W has sorted it or not. We have a link running Fibrestore SFP+ DWDM 80km modules in two CCR1072. The link works fine when manually negotiated to 1gpbs but on auto it will not connect when manually or automatically set to 10gbps. Fibre attenuation is well within spec for these modules.

Any ideas to try?

CCR1072. can be configured to support 1Gbps but not 10Gbps, have you consult with the mikrotik technical support? or you can look st this ... 092438.pdf

According to the pdf,
SFP+ ports of this router do support 10GBASE-SR and 10GBASE-LR modules, 10G Direct Attach Copper (DAC)., I1000BASE-SX and 1000BASE-LX. SFP., but it doesn't mention the CWDM SFP+. So maybe it is the problem here. :)
